摘要:
A card according to the invention includes an external hard coat layer (108) which when exposed to intense heat tends to crack, an internal core layer (102) which can be personalized with a laser and which develops intense heat at points being lasered, and at least one plastic buffer layer (110, 112) between the external hard coat layer and the internal core layer to absorb and dissipate the heat energy produced at and within the core layer when being personalized with a laser and functioning to block the heat energy and preventing the cracking of the external hard coat layer. The invention further comprises a method for enabling the personalizing of cards having an external hard coat layer overlying an internal core layer which is to be personalized and wherein the laser beam has to pass through the hard coat layer before impacting the internal core layer, comprising forming at least one buffer layer between the hard coat layer and the core layer. Said buffer layer is characterized in that it can absorb energy and heat imparted to the internal core layer by a laser and prevent the heat generated due to the laser from adversely affecting the hard coat layer.

A multi layered card embodying the invention includes an outer layer of an amorphous laser reactive copolymer material which is embossed with a selected pattern at a selected temperature which is above the glass transition temperature, Tg, of the copolymer and below its melting temperature, Tm. So embossed, the selected pattern is set in the copolymer layer, and its external shape cannot be changed from the embossed form to which it was set at the selected temperature, without destroying the selected pattern. The outer layer may be laminated with the other layers of the card and laser engraved before or after lamination.

A transaction card includes a monolithic ceramic card body having one or more pockets, and at least one of a magnetic stripe, a barcode, and a laser signature portion. The one or more pockets may be configured to receive at least one of the magnetic stripe, the barcode, a contact chip module, a contactless chip module, a dual interface chip module, a booster antenna, a hologram or commercial indicia. A transaction card may also include a substrate layer having a first side and a second side. A first ceramic layer is connected to the first side of the substrate layer.

Cards made in accordance with the invention include a specially treated thin decorative layer attached to a thick core layer of metal or ceramic material, where the thin decorative layer is designed to provide selected color(s) and/or selected texture(s) to a surface of the metal cards. Decorative layers for use in practicing the invention include: (a) an anodized metal layer; or (b) a layer of material derived from plant or animal matter (e.g., wood, leather); or (c) an assortment of aggregate binder material (e.g., cement, mortar, epoxies) mixed with laser reactive materials (e.g., finely divided carbon); or (d) a ceramic layer; and (e) a layer of crystal fabric material. The cards may be dual interface smart cards which can be read in a contactless manner and/or via contacts.
